DOOR-CHECK.

SPECIFICATION forming part of Letters Patent No. 241,190, dated May 10, 1881,

Application tiled November 3, 1880.

To all whom it may concern Be it known that I, JACOB H. OOFFMAN, of Philadelphia, inthe county ofIhiladelphia and State of Pennsylvania, have invented certain new and useful Improvements in DoorOhecks; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference beinghad to the accompanying drawings, and to letters of reference marked thercon,which form a part of this specification, and in which- Figure l is a perspective view of my doorstop as applied for use, and Fig. 2 is a partly sectional and side view thereof.

This invention has relation to improvements in that class ot' door-stops employing a springbolt and a catch to secure the doorin an open position as against being accidentally closed by the action of the wind or other force.

It consists cfa beveled spring-bolt combined with a notched catch or stop, and ofthe coinbination, with the bolt, of an operating device, substantially as hereinafter more fully set forth.

In the accompanying drawings, Aindicates a bolt inclosed in a suitable case, a, which is applied in the present insta-nce to the door and through its lower end is an opening, I), coinmunicating with a recess, b', in the doorin rear of the case. The boltis beveled, with its slope extending downwardly and rearwardly, and is acted downwardly upon by a spring, c, within the ease a, to cause it to lock the catch after its beak passes the point of the bolt, which operation secures the door in an open position. A stud or projection, d, on the bolt Aextends through a slot, d', in the case c and affords a means for the attachment of the rod, chain, or cord d2, for releasing the bolt from the catch or stop without stooping when desired to close the door. The rod cl2 is connected to a sliding knob, el?, by moving which upwardly to over- (No model.)

come the action of the spring the bolt is disengaged from the catch on the stop.

B is the stop, suitably located with relation to the door, and with a notched beveled catch, e, inserted into its outer cnd,with a surrounding elastic cushion, e', to break the concussion asthe bolt and catch come together upon throwing or swinging the door open. The notch in the catch ot' the stop, the moment its beak passes the downward] y-pressin g bolt, receives the point ofthe holt and secures thc parts together as against the action ot' the wind or other force, accidentally shutting the door. Further, it will be noticed that the shoulder of the catch, or rather ot its notch, will sustain such a relation to the point of the bolt when in engagement that it will be impossible forthe two to become disengaged, and thus fail to secure the door, as is liable to arise with the use of a doubleheveled bolt, or such a bolt and a perforated catch or eye, as disclosed by the previous state of the art. 65

I am aware that bolts and catches having inclined surfaces, and either or both having' springs to hold them with a constant force in one direction, have been before used, and all constructions, embodying such dcvices,broad 7o ly, are not sought to be covered in this application.

What I claim as new is- In a door-stop, the recessed door and case a fitting therein, the opening l), and recess b', 75 the bolt A, having stud el, operatingin slot d', the spring c, cord d2, and knob d3, in combination with the stop B, having flexible cushion c, and catch c, all constructed, arranged, and adapted as and for the purposes set forth.

In testimony that I claim the foregoing I have hereunto setV my hand.

JACOB H. GOFFMAN.
